DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suspending curtain fabric of a lift-up curtain.

[0002]

2. Description of the Related Art Conventionally, as one type of a curtain, a curtain cloth is suspended and supported from a head box attached to a window frame or the like, and an operating device provided in the head box is operated. There is one that can be lifted from the lower edge.

As an apparatus for suspending the curtain fabric, there is a device in which a hook-and-loop fastener is attached to an upper end of the curtain fabric and a front surface of a head box, and the curtain fabric is adhered to the head box by the hook-and-loop fastener.

[0004] With this configuration, the curtain fabric can be easily adhered to the head box at the installation site of the lift-up curtain, and the work of assembling the lift-up curtain can be easily performed.

[0005]

In the apparatus for suspending curtain fabric as described above, a hook-and-loop fastener is adhered to the upper end of the curtain fabric and the front surface of the head box with a double-sided tape. Therefore, the double-sided tape adhered to the head box due to the weight of the curtain fabric as it is used is easily peeled off from the front surface of the head box at both ends of the head box.

As a result, there is a problem in that both ends of the upper end portion of the curtain material hang down from the head box, and the appearance is deteriorated. An object of the present invention is to provide a lift-up curtain that can prevent peeling of curtain fabric from a head box while using a hook-and-loop fastener.

[0007]

According to a first aspect of the present invention, in a lift-up curtain in which an upper end of a curtain fabric is bonded to a head box with a hook-and-loop fastener, both ends of the hook-and-loop fastener bonded to the head box are attached to the inside of the head box. Then, the hook-and-loop fastener was sandwiched and fixed between the fitting member to be fitted into the end of the head box and the inner surface of the head box.

According to the present invention, a gap for holding the hook-and-loop fastener is provided between the fitting member and the inner surface of the head box. In the third aspect, the hook-and-loop fastener can be attached to the front face of the head box and the inner face of the head box via a double-sided tape, and the hook-and-loop fastener is sandwiched between the fitting member and the inner face of the head box. Fixed.

According to a fourth aspect of the present invention, the fitting member has a built-in operating device for raising and lowering the curtain fabric, and an operating portion case fitted into one end of the head box.
And a cap fitted to the other end of the head box.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the lift-up curtain shown in FIG. 1, a curtain fabric 2 is suspended from a head box 1 fixed to an upper frame of a window or the like, and a weight bar 3 is provided at a lower end of the curtain fabric 2. Hanging supported.

A plurality of lifting / lowering cords 4 are suspended from the head box 1, and the lower end of the lifting / lowering cord 4 is attached to the lower end of the curtain fabric 2 via a mounting member 5.

The upper end of the lifting cord 4 is supported by a lifting cord winding device (not shown) provided in the head box 1. Then, by operating the ball chain 6 hanging down from one end of the head box 1 to drive the elevating cord winding device, the elevating cord 4 is wound up or unwound. Therefore, the curtain fabric 2 is moved up and down by operating the ball chain 6.

The upper end of the curtain fabric 2 is bonded and fixed to the front surface of the head box 1 with a hook-and-loop fastener. 2 and 3, a hook-and-loop fastener 7a is attached to the back surface of the upper end portion of the curtain cloth 2, and a hook-and-loop fastener 7b is provided on the front surface of the head box 1 with a double-sided tape. It is stuck on. Then, the curtain fabric 2 is suspended and supported from the head box 1 by bonding the hook-and-loop fastener 7a to the hook-and-loop fastener 7b. In addition,
On the front surface of the head box 1, a ridge 1a for guiding the lower edge of the attachment position of the hook-and-loop fastener 7b is formed.

The hook-and-loop fastener 7b attached to the front surface of the head box 1 is formed to be longer than the entire length of the head box 1, and a portion which extends laterally beyond the end of the head box 1 is provided inside the head box 1. The head box 1 is folded and held between the inner surface of the head box 1 and the operation unit case 8 or cap 9 fitted to both ends of the head box 1.

The operating portion case 8 is for rotating and driving a drive shaft 10 for driving the elevating cord winding device based on the operation of the ball chain 6, and a pulley on which the ball chain 6 is mounted. In addition, a self-weight drop prevention device for preventing the curtain fabric from falling by its own weight is built in.

Projecting ridges 12 projecting laterally are formed on both upper and lower ends of both sides of the insertion portion 11 inserted into the head box 1, and the insertion portion 11 is inserted into the head box 1. In the inserted state, a gap for holding the hook-and-loop fastener 7b is secured between the side surface of the insertion portion 11 and the inner surface of the head box 1.

Accordingly, if one end of the hook-and-loop fastener 7b is folded back into the head box 1 and adhered to the inner surface thereof, and the insertion portion 11 is inserted into one end of the head box 1, as shown in FIG. Then, one end of the hook-and-loop fastener 7b is sandwiched and fixed between the fitting portion 11 and the inner surface of the head box 1.

As in the case of the operation section case 8, the cap 9 is formed with ridges 14 projecting laterally at upper and lower ends on both sides of a fitting portion 13 fitted into the head box 1. In a state where the insertion portion 13 is inserted into the head box 1, a gap is secured between the side surface of the insertion portion 13 and the inner surface of the head box 1 for holding the hook-and-loop fastener 7 b. .

Accordingly, if the fitting portion 13 is fitted to the other end of the head box 1 in a state where the other end of the hook-and-loop fastener 7b is folded back into the head box 1 and adhered to the inner surface thereof, FIG. As shown, one end of the hook-and-loop fastener 7b is sandwiched and fixed between the fitting portion 13 and the inner surface of the head box 1.

[0020] With the raised curtain configured as described above, the following operational effects can be obtained. (A) One end of the hook-and-loop fastener 7b adhered to the front surface of the head box 1 is folded back into the head box 1 and sandwiched between the fitting portion 11 of the operation unit case 8 and the inner surface of the head box 1. It is fixed. Also, hook-and-loop fastener 7b
Is folded back into the headbox 1 and is clamped and fixed between the fitting portion 13 of the cap 9 and the inner surface of the headbox 1. Therefore, peeling of both ends of the hook-and-loop fastener 7b from the front surface of the head box 1 can be reliably prevented, so that peeling of the curtain fabric 2 from the head box 1 can be reliably prevented. (B) Since the hook-and-loop fastener 7b is sandwiched and fixed between the side surfaces of the insertion portions 11, 13 and the inner side surface of the head box 1,
The dimensions between the inner surfaces of the head box 1 and the insertion portions 11, 1
Even if there is an error in the dimension in the width direction 3, the hook-and-loop fastener 7 b functions to absorb the dimensional error, so that the insertion portions 11 and 13 can be securely fitted and fixed to the head box 1. (C) The end of the hook-and-loop fastener 7b is folded back into the head box 1 and stuck, and the fittings 11 and 13 of the operation case 8 or the cap 9 are inserted. Since both ends of the hook-and-loop fastener 7b can be easily held and fixed in the head box 1 without requiring a specific jig or the like.

The technical ideas other than the claims described in the above embodiment will be described below together with their effects. (1) In any one of claims 1 to 4, a ridge is provided on a front surface of the head box to guide a sticking position of the hook-and-loop fastener. It is possible to easily attach the hook-and-loop fastener to the front face of the head box.
